Abstract
A method of peritoneal dialysis includes introducing a dialysis solution into a peritoneal cavity; allowing the dialysis solution to dwell in the peritoneal cavity for a period of time to provide diffusion through an inner lining of an abdominal cavity with exchange of components between a microcirculation of a peritoneum and a dialysis fluid; withdrawing the dialysis solution from the peritoneal cavity with toxins; passing the dialysis solution with toxins through an absorbent polymeric material which has a size, shape, and structure selected so as to remove the toxins in a molecular range of 300-30,000 Dalton from the spent dialysis solution; and returning the thusly purified peritoneal dialysis solution to the patient.
